Web containers in application servers normally use a server thread per client request. To develop scalable web applications, you must ensure that threads associated with client requests are never sitting idle waiting for a blocking operation to complete. Asynchronous Processing provides a mechanism to execute application-specific blocking operations in a new thread, returning the thread associated with the request immediately to the container. For example, if a client is submitting a large HTTP POST request over a slow network connection, the server can read the request faster than the client can provide it. Put the request in asynchronous mode as described in Asynchronous Processing. Table describes the interfaces for read listeners and write listeners.

There are a lot of examples in the internet about servlet 3. We can use it in Spring very easily. We just have to return DefferedResult or CompletableFuture. But I can't find example of usage servlet 3. But I can't find the example of that Listeners.
Introduction To Java Servlets and Its Life-Cycle
The canonical reference for building a production grade API with Spring. If you have a few years of experience in the Java ecosystem, and you're interested in sharing that experience with the community and getting paid for your work of course , have a look at the "Write for Us" page. Cheers, Eugen. In this article, we will have a look at a core aspect of web development in Java — Servlets.
